(CL ISL-'21) "pastecan be appliedfgradually or abruptly ac- Claims.

This invention relates to cigar machines, and

Y'more particularlyv to pasters for cigar rolling machines, its object being to provide an automatically controlled precision device with complete- 'ly enclosed and readily demountable paste-carry- -ing parts insuring cleanliness and high efficiency of operation, being designed for delivering a defnitepredetermined amount of paste upon'a Itobacco leaf at the proper moment in each cycle of the machine, provided there is a leaf present 'to receive the paste.

There are two operations in a cigar machine *which require the'application of paste: the rollshaped rolling table. In this case, the paste must be applied from above by a movable'arm, so as to clear the path for the next binder after, the paste has been delivered. In the wrapping operation, the wrapper leaf is held affixed by suction to' the'wrapper carrier which halts for a moment 'on its Way to the Wrapping device to receive the paste, hence the latter is usually applied to the 'wrapper from below at the fixed dwell position of the carrier, preferably in the shape of a loop following the contour of the flag end of the wrapper.

To meet these differing conditions, the design of the improved paster is carried out both for vupward delivery of a paste loop from a fixed position, and for downward delivery of a Y paste "spray by a nozzle moved to and from the delivery position at each application.

It is anadditional object of this invention to provide an improved pasting mechanism for applying paste to Wrappers and binders in which the paste reservoir and the paste conveying duct associated therewith are easily removable from the cigar machine upon which they are located for cleaning, interchange of parts and repairs.

It is a further object of the invention to provide means for building up pressure 'in the paste Areservoir at the start of operations in order to force paste into the paste line whenever the mechanical paste feeding means is not in operation. This structure may assume the form of a priming pump suitably mounted on the paste reservoir.

It is an added object of the-invention to provide a Apaste applying mechanism for applying paste to wrappers and/or binders in which the in the adhesive applying head thereof is moved into adhesive applying position by means other than mechanical, such for instance as hydraulic means, and additional mechanism is provided for controiling the flow of adhesive from said head -at the conclusion of its movement to adhesive kapplying position.

The invention also consists inthe provision of -a novel adhesive applying mechanism having an adhesive applying head, which head is moved by aYA hydraulic pressure into adhesive applying position, and also in valve mechanism which is hydraulicallyoperated to control the flow of adhesive from-said'head. y y n @With these and other objects not specifically mentioned in View, the invention consists in certain constructions and combinations which will vbel-hereinafter fully described and then particularly-pointed out in the claims hereunto kappended.

Referring to Figs. 1, 2 and 3, the housing I2 which is suitably attached to the base I3 of the cigar machine, carries the closed paste reservoir I4, a paste-forwarding plunger I5, and a rock shaft I6 which mounts the automatically controlled operating arm I1. 'I'he paste reservoir I4 rests on the top of housing I2 and is secured in place thereon by a spring-tensioned ball I8 fitting into a recess provided in an extension |9 of the reservoir when the latter is pushed into a seat in housing I2 provided for this purpose. Through this construction, when it is desired to remove `the reservoir for refilling or cleaning, it is only necessary to apply a horizontal pull to the paste reservoir to remove it from its supports in housing I2, after the paste-delivering parts .have been disconnected from their support 50. See Fig. 1.

The paste reservoir |4 at its bottom has a bushed horizontal outlet or bore 2| in which the plunger I5 reciprocates through the medium of lever I1, as shown by dotted lines I5' in Fig. 1. In the wrapper paster, lever I1 is attached by a ball-and-socket joint 22 to a connecting rod 23 which in turn is afliXed (see Figures 1 and 2) by a ball-and-socket joint 24 to a cam lever 25 held by a spring 26 against the surface of a cam of the cigar machine similar to that shown in Figs. 12 and 13. At the proper moment in every cycle of the machine, cam lever moves arm .I1 into dotted position I1 (Fig. 1) against an adjustable stop-screw 21 in housing I2. This screw has a grooved head with which engages a locking spring 28, and serves to adjust the stroke of plunger I5 which governs the quantity of paste delivered. As shown, the plunger I5 has secured thereto a rectangular collar 29 slidableon guide surfaces provided in housing I2. A springr30 coiled about plunger I5 bears against housing I2 and collar 29 and thereby normally tends to urge the plunger forward to paste feeding position. The forked ends of arm I1 bear against collar 29 on each side of plunger I5 and hold the latter in non-active position against the pressure of spring 30 as long as the cam lever 25 is inactive.

In the rest position of plunger I5, as shown in Figs. 1 and 10, the collar 29 engages with a depression formed in each of two bell-crank latch levers 30| and 3| fulcrumed on a shaft 32, supported in housing I2, and held in upward tension by stops 33 pressed against them by springs bearing against adjustable sockets 34 by means of which the tension applied to latch levers 30| and 3| is controlled. The lever 30| is connected by a rod 35 with a piston 36 closing a chamber 31 in housing I2, this chamber communicating by a pipe 38 with the suction system of the cigar machine and by a pipe 39 with the suction chamber of the Wrapper carrier. When awrapper covers the suction holes in the bottom of the head H of the carrier, the suction in chamber 31 is strong enough; to pull down piston 36 and thus to Aunlatch one side of collar 29 as vshown in Fig. 1. But when the suction holes of. carrier head H are open through the failure of a proper wrapper pick-up, most of the suction in pipe 38 is spent through pipe 39, leaving in chamber 31 an amount insuiicient to depress lever 30|. Therefore, where no wrapper is present on the wrapper carrier head, no paste will be forced from the applier because plunger I5 will be locked in inoperative position by latch 30|.

The action of cam lever 25, at the proper moment, causes the arm I1 to be pulled into position I1' in which a pin 40 carried between its fork ends, engages a nose 4| at the end of latch lever 3|, thereby depressing it, as shown in dotted lines, and frees the collar 29, provided the lever 30| is held down by suction on piston 36. The spring 30 then pushes the plunger I5 against the fork ends of arm I1, thereby forcing a given quantity of paste into the outlet 2| of the reservoir. With this arrangement, the plunger I5 remains at rest until the arm I1 has reached the end of its stroke, and then advances in one quick jump. However, the latch lever 3| and the tripping pin 40 may be omitted, in which case, when lever 30| is unlatched, the plunger I5 immediately follows the movement of arm I1, thus delivering the paste in a more gradual manner, which is preferred in applying paste to the wrapper.

This modified form of the invention is shown in Figs. 12-15 and is similar to the invention shown in Figs 1 and 2 except that members 3|, 40 and 4| have been omitted therefrom. Members 40|,.4I2-4I5, 4I1-430, 432-439, 442-452, 454, 456-458, 462, 463 and 463a perform operations which are similar to those performed by the corresponding elements shown in Figs. 1 and 2 and for this reason a more detailed'explanation is deemed unnecessary since suchexplanation has already been given in connection with Figs. 1 and 2.

A conventional cam device, which will give a simple reciprocating movement during each machine cycle (such as the type shown in the Belot Patent No. 1,128,093), is provided for actuating the lever arm i'l. A detailed view of such conventional cam device is shown in Figs. 12 and 13.

A conventional cam 496 having a single indented portion 491 is mounted on a shaft 498 of the cigar machine and makes one complete revolution for each cycle of the cigar machine. A cam follower 495 mounted on theA spring tensioned arm 425 is held against the cam by means of spring 426. The arm 425 is pivotally mounted at one end to the support 4|3; and the other end, by means of a ball and socket joint 424, imparts a simple reciprocatory movement to the rod 423 during each-cycle of the cigar machine. The rod 423 in turn, also by means of a ball and socket jointV 422, imparts a simple to-and-fro movement to lever 4I1 during each cycle of the cigar machine.

When the suction holes of the carrier head H are closed by means of a Wrapper being carried thereby, sufcient suction is created to cause the lever 40| to be unlat'ched; whereupon the collar 429, Xedly mounted on plunger 4|5, immediately follows, under the pushing action of spring 430, the withdrawing movement of arm 4I1. The displacement of thepaste is in this manner alwaysunder control. As already mentioned, the rate at which the lever 4|1 travels is controlled by means of the cam device shown in Figs. 12 and 13. Such a controlled displacepaste is being applied to a' wrapper in order to aevmee 3- avoid unnecessary splashing which otherwise might cause discoloration of a wrapper.

From outlet 2|, the paste 'passes through a demountable pipe-elbow 42 and a connectingl pipe 43 `into a T 44 from which it entersr the delivery member 45. The elbow 42 is held in the reservoir outlet by a spring-tensioned ball 46 engaging with a V-groove in the shank of the elbow, so that it can readily be demounted by an up-ward pull. The elbow 42 vcommunicates with outlet 2l by a horizontal inlet opening 41, see Figs, 4 and 5. By releasing the clamp screwy 48, the pipe 43 can be withdrawn from elbow 42. The T 44v is loosely mounted on a collared stud 49 clamped in a slotted bracket 50 supported on a post 5I attached to bedplate I3, the

flexible nature of this arrangementr facilitating the convenient adjustment of the position of the paste-delivering member 45. It will be obvious that the construction and arrangement of the parts of this device are such that they can be assembled or taken apart with great rapidity and that it is a relatively simple matter to clean them if paste handled therein should tend to congeal and clog the line.

In the T 44, Figs. 1, 6 and 7, is clamped a pipe 52 communicating by an opening 53 (Fig. 9)

with pipe 43, and on pipe 52 is slidably mounted` a sleeve 54 closed by a spring-tension valve 55 in a nozzle 55. To pipe 54 is clamped a collar 51. Figs. 6 and 7, connected with T 44 by a spring 58, the said collar being slidable on a guide pin 59 carried by a lug of T 44. To the nozzle 58 is attached the paste delivery member, Figs. 8 and 9, consisting of a closed, elongated delivery element 45 shaped to conform to the configuration of thev flag of the wrapper, and provided with a plurality of openings 6I along its surface through which paste is expelled for application to a wrapper. A plurality of ducts 6I! conduct the paste from nozzle 56 into the applying head 45. The paste forced by the plunger I5 into the elbow 42, on entering the already filled pipe 52 raises sleeve 54 which is vertically slidable on pipe 52 upwardv against the pressure of spring 58, which normally maintains sleeve 54 correctly positioned on pipe 52. Delivery head 45 is raised in this manner hydraulically until it contacts with a wrapper on carrier head I-I. When the upward movement of head 4.5 has been checked by lengagement with a wrapper positioned upon the carrier head, the continued pressure of the paste exerted upon valve 55 causes spring 55B to be compressed, whereupon the valve opens and paste is extruded from the nozzle 55 into the paste delivery head 45 thereby adding to the supply of paste in the applying head 45, and paste is forced through the openings 6I of head 45 on to the wrapper. Valve 55 is arranged with its stem portion projecting into the paste line. (See Fig. 9.) By means of this construction, paste will not be allowed-to dry on or clog the valve stem 'of the paste line and the valve operating mechanism. Consequently, this structure is rendered more efficient than any similar device heretofore known. If desired, openings 5I located a distance from ducts 50, may be formed larger in diameter than those directly adjacent thereto which allows lfor a more equal distribution of the paste extruded from member 45.

In order to ll the entire paste-carrying sys-` tem before starting the operation of the cigar machine, a small priming-pump 52 is mounted in an opening provided for this purpose on top of theV paste reservoir I4.. The.- pump .is screwed tightly in its sockets inthe reservoir (Fig. 1) when paste is to be forced by air pressure intov the paste line. After pastel feed. has started, the pump is unscrewed and the entrapped air is a-llowed to escape through port 63, which allows-the port 63a formed'in the reservoircasting to come into communication with port63 in the pump.

In the binder paster, Figs. 10 and 11,*the operatingyarm H1 is actuated by a vertical rod 64 controlled by a cam of the cigar machine (not shown). As in the wrapper paster, paste forced by a-plunger II5 into the outlet I2I of a reservoir I I4, enters through an opening 65 into the vertical shank of a pipe elbow 66 which in this case is swingably inserted into bushings 51 in the outlet of reservoir II4 and at its lower end-carries a fixed collar v68. A pipe 69 clamped into elbow 65 carries the paste to the delivery nozzle 1i) from which it is squirted through holes in a cap 1I upon the binder leaf held on the rolling apron A of the cigar machine upon having been brought into position by the action of operating arm II1. A spring-tensioned valve 90 is inserted into nozzle 10 to obviate eventual dripping of paste on the cessation of the forward stroke. of plunger II5, and to prevent air from sucking in on its return stroke. The valve construction and its operation is similar to that described in connection with nozzle 56 of the wrapper pastev applier. f

On the shaft I5 is xedly mounted a gear -segment 12 meshing with a bevel gear. 13 loose on a horizontal shaft 14. turning in a bushing 15 fast in housing 15 which is similar to housing I2 of Fig. l. From gear 13 projects 'an axial pin 11 against which bear strong springs 18 adjustably supported in a collar 19 fast on shaft 14.

`Shaft 14 has a bevel gear 8B in mesh with a bevel gear 8| on a vertical shaft 82. turning in housing 15 and having a xed collar 83 carrying an adjustable stop screw 84 engaging with a pin 85 in housing 16 when the nozzle 15 is in delivery position. A vertical pin 85 in collar engages with a slot in collar', thereby transmitting the motion of shaft 52 to elbow 55 and to theswinging arm 69. The swing of arm 59 having been adjusted by stop screw 84, any excess motion of arm 12 is absorbed by the springs 18 in collar 19. The pin 11 and collar 15, as well as pin 83 and stop screw 84 maybe omitted and the gear 13 mounted iixedly on shaft 14, in which case the angular position of arm 69 in bushings 61' must be accurately adjusted with reference to the endv of the stroke of arm 12 before fastening collar 68 to it. The gears 80 and 8| are protected by a cover 51 attached to housing 16. The mechanism just described makes it very simple to remove reservoir I I4 and paste applier 1I from the machine for cleaning or other purposes. In demounting the reservoir H4 it is moved to the right in Fig. l0, off bushing QI which also performs the function of aligningVV the shafts 65 and 82 and the collar 68 slides out of engagement with pin 85, and leaving the paste'delivering arm 69 attached to the reservoir for separate demounting, if required.

The stroke of plunger I I5 in this case is adjusted by a grooved nut 8B, held-in placefby a locking spring 89 attached to the end' ofthe plunger. The suction pipe |38y in Fig. l0 has a branch connected to the suction chamber of the rolling apron A, so that in this case the latch' lever 301 is controlled by the presence of a binder on the rolling apron and if-abinder be not presentno paste--is fed through nozzlei 90:" Although it is preferred to apply paste to the binder with a quick spraying action, pin |40 and latch |3| may be omitted if a gradual action of plunger I l is preferred, in order that plunger |5 may be moved forward under action of spring |30 during forward travel of arms against which collar |29, fixed to the plunger, is pressed. In applying paste to the binder, however, it is usually preferred to spray it upon the binder, and hence the latch |3| and pin |4| are both used.

It will be noted that the arangement of parts of the improved pasting mechanism of this invention is such that the hydraulic portion thereof, that is, the paste supply with its conduits and applier can be removed from its support and actuating mechanisms without ditsurbing any of the elements thereof. Referring to Figs. 1 and 10, it Will be seen that paste supply tank |l4 is detachably mounted upon housing 'I6 in which are located levers |3| and Sill, and also suction pump |37 and plunger |35 which controls the operation of plunger |5 reciprocable therein. Since these actuating elements are all mounted within the housing 1S, it is obvious that no dust or dirt can work into this housing and accumulate 'on the several actuating elements above mentioned, thereby minimizing the wear and tear on these parts and the necessity for frequently cleaning them in order to maintain the paster at its greatest efficiency of operation.
